Page 7: Product Description
Functional Safety KCD2-SR-(Ex)*(.LB)(.SP), HiC282* Product Description Product Description Function KCD2-SR-1.LB(.SP) This signal conditioner provides the galvanic isolation between field circuits and control circuits. The device transfers digital signals (NAMUR sensors or dry contacts) from the field to the control system. The proximity sensor or the mechanical contact controls the normally open relay output for the control side load. - Page 8 Functional Safety KCD2-SR-(Ex)*(.LB)(.SP), HiC282* Product Description KCD2-SR-2(.SP) This signal conditioner provides the galvanic isolation between field circuits and control circuits. The device transfers digital signals (NAMUR sensors or dry contacts) from the field to the control system. The proximity sensor or the mechanical contact controls the normally open relay output for the control side load.
- Page 9 Functional Safety KCD2-SR-(Ex)*(.LB)(.SP), HiC282* Product Description HiC2821 This isolated barrier is used for intrinsic safety applications. The device transfers digital signals from NAMUR sensors or dry contacts from the hazardous area to the non-hazardous area. The proximity sensor or the mechanical contact controls the normally open relay output for the control side load.

Page 15: Useful Life Time
As noted in DIN EN 61508-2:2011 note N3, appropriate measures taken by the manufacturer and plant operator can extend the useful lifetime. Our experience has shown that the useful lifetime of a Pepperl+Fuchs product can be higher if the ambient conditions support a long life time, for example if the ambient temperature is significantly below 60 °C. - Page 16 Functional Safety KCD2-SR-(Ex)*(.LB)(.SP), HiC282* Planning Maximum Switching Power of Output Contacts The useful life time is limited by the maximum number of switching cycles under load conditions. The maximum number of switching cycles is depending on the electrical load and may be higher when reduced currents and voltages are applied. You can see the relationship between the maximum switching power and the load conditions in the figures below.
